Don't be fooled by that co-op tag, this game is NOT co-op in any enjoyable way. Unless you enjoy watching your friend do complicated, drawn-out puzzles for 20 minutes then do not play this game with others. There is no split-screen or way to view your character while your friend plays theirs, you can only view one at a time. During certain parts of the game it forces you to play a single character for an entire level, leaving any friends you might be playing with to sit and be forced to watch you try and figure it out for the entire duration.
The levels are also unnecessarily big for what they need to be, leaving you to run around up and down ladders and ropes just to extend the play time. This game might be enjoyable by yourself if you like running/climbing simulators, but I didn't find anything enjoyable about it at all. I'm glad I bought it on sale and it's definitely not worth the standard price.
